SPECIFICATION forming part of Letters Patent N 0. 648,783, dated' liliay '1 900. I

Application filed December 18, 1899. Serial N... 740,700. (No model.) V

;l ing sand to the rails under a locomotive in.

it order to prevent the slipping of the wheels; and it has for its object a device of this character which will be sure and efficient in operation one which can be readily transformed from a pneumatically-operated sander to a r straightevay device in case the pneumatic apparatus should get out of order, and one in ,which the air-ducts and sand-cup can easily the kept free from being clogged up.

The invention consists in certain details of .20 construction and arrangement and combination of the parts, which I shall" hereinafter specifically describe and claim.

Reference is to be had to the accompanying drawings, forming part of this specification,

2 5 in which like characters of reference indicate corresponding parts in all the views.

Figure 1 is an elevation of a portion of a locomotive with one'of my improved sanding devices attached. Fig. 2 is a sectional view of the sand trap and cup with parts in elevation, the cup being shown in inverted position. Fig. is a sectional view of the same with the sand-cup in position to receive a jet of air. Fig. l is an elevation of the sand-trap and air-jet casing. Fig.6 is a perspective view of a lever used to invei t the sand-cup, and Fig. 6 is a plan view of the sand-cup shown detached.

My improved sanding device consists of a which serves as the sand-trap and is formed with an upper tubular arm or extension 10$, secured by means of a pipe-nipple to the lower side of the sand-box A, and a lower arm or extension 10", in which the delivery-pipe B, leading to the rail, is secured. The casing 10 is provided with a removable cap-section 10, secured thereon by machine-screws or other suitable fastenings', and through the opening formed by the removal of said seclion is inserted my improved sand-valve,

hollow approximatelyspherical; casing .10,-

which is in the form ofa spherical cup 11, formed with a body portion which is approximately spherical and is formed with a sphere ical concavity or pocket 11", having a mouth '55 11 and a tubular trunnion or axis 11", fitted 'sn ugly in the upper arm 10 of thecasing, communication being thus. established through the cup between the interior of the sand-box and the basing-and delivery-pipe. The-cup" 6o 11 is also formed with.anaxially-oppositetri: hular trunnion 11, over which the section 10 is fitted, the latter being formed with an opening 10', through which. a; reduced extension 11 0f the trunnion 11 projects. In its norinal position the said cup ll has its mouth 11* at the top, and an air-jet casing'l'fl is secured,

preferably by screw-thread engagement, in the casing 10 and extends at oblique angles to the. axis of the sand-cup; 11, with its inner. 79

end directly opposite themouth 11. The jet-casing 12 has a longitudinal opening ',extending therethrough and; oppositelateral openings leading into the longitudinal openl ing, the latter being counterb'ored above such 7 5 lateral openings and having inserted therein an upwardly spring-pressed valve 12,- working in a bushing 12, screwed into the upper I end of the jet-casing. The valve 12 is formed with a cleaning-point 12 at its lower end, 80 adapted to pass through the orifice l2 'whenever thevalve is manually depressed in order to keep the said orifice clean.

Air is injected through the et-casing by means of'a branch air-pipe C, which has one I end screwed into one of the lateral'openings in the jet-casing 12 and is connected with a main air-reservoir (not shown) by a main air pipe D. There is also connected to the main air-pipe another branch'pipe E, leading to a sanding device on theother sideof thesand-zbox, which being similar to the one herein described I have not deemed it necessary to show.

13 designates a plug fitted in the lateral 93 opening in the jet-casing opposite the branch air-pipe C, so that the saidpipem'ay be blown out when desired to remove-scale or the like. i

In the ordinarywpefation' of my'device a 'jet'of air (or steanr'ljsf'injected through the m main pipe D under the control of the engineer into the branch pipes and thence through the air-jet casing 12 into thcsand-cup 11, which operation raises the sand from the cup in a cloud and scnds'it through the delivery-pipe B to the rail.

A 'nut 14 screws into the extension 11 of the. cup-trunnion llyiand through this nut passes a wire rod 15,;w'hich extends fromdhe not up into the sand-box and is vibrated by the movement' of the locomotive, thereby keeping the sand in the passage leading to the on p always loose.

For the purpose of transforming the pneuinatic sanding apparatus described above into a straightway sander on accountof a breakage in the air system and for the purpose of emptying the sand-cup 11 to clean it I provide a lever 16, which consists of a polygonal head 16, inserted over a correspondinglyshapcd portion of the trunnion extension 11, and a curved handle 16", by which it may be operated, to. turn the sand-cup upside down for the purposes just mentioned above. The nut 1i holds the lever-in place, and the latter is limited in its movement by steps 17 17, formed on the casing 10.

The inverted position ofthe sand-cup is shown in Fig. 2.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is- V 7 1. In a track-sanding device, a holloweasing having a tubular extension forming an inlet for the sand, a sand-cup having a trimnien fitted. in said inlet, said cup beingformed with an upwardly-extending mouth and an opening leading therefrom through the said trunnion, and an air-injectingdevice in said casing directly opposite the mouth of the cup, as set forth.

2. In a track-sanding device, a spherical casin g arranged for connection to a sand-box, a sand-cup in said casing havinga spherical body portion spaced from the' casing and formed with a spherical concavity having a mouth, and an air-injecting device in said casing and pointing radially toward the mouth of said concavity, as set forth.

In a track-sanding device, a casinghavingv a tubular extension by which it is connected to a sand-box andan openingoppositc said extension, a sand-cup having a hollow trunnion fitted in said tubular extension and an opposite trunnion fitted in said opening,
